Chapter 3. Configuration File Blocks for DMF

Chapter 3. Configuration File Blocks for DMF
Prev

Configuration parameters for FailSafe DMF must be specified in the configuration file /var/ha/ha.conf. The sections in this chapter describe each DMF-specific block defined in the FailSafe DMF template file /var/templates/ha.conf.dmf. This file is modified and appended to /var/ha/ha.conf as described in “Adding DMF Information to the FailSafe Configuration File” in Chapter 2.

The examples in this chapter show the DMF configuration file blocks discussed in “Adding DMF Information to the FailSafe Configuration File” in Chapter 2.

DMF Application-Class Block

The following example shows the application-class block in a DMF configuration. The cluster contains the machines cm1 as the server (primary) node and cm2 as the backup node.

Example 3-1. Application-Class Block

application-class dmf
{
        server-node = cm1
        backup-node = cm2
}

DMF Action and Action-Timer Blocks

The following example shows the action and action-timer blocks for DMF.

Example 3-2. Action and Action-Timer Blocks

The action block specifies the path names of the local monitoring script and the action-timer block specifies default monitoring timing and timeout values for the monitoring of the DMF daemon.

action dmf
{
        local-monitor = /var/ha/actions/ha_dmf_lmon
}
action-timer dmf
{
        start-monitor-time = 60
        lmon-probe-time = 120
        lmon-timeout = 60
        retry-count = 1
}

The parameters used in action and action-timer blocks for DMF are as follows:

`local-monitor`		The path name of the local monitoring script for DMF. Do not change this value.
`start-monitor-time`		Specifies the amount of time that the application monitor waits before it starts using the local monitoring script to monitor the DMF daemon.
`lmon-probe-time`		Specifies (in seconds) how often local monitoring of the DMF daemon is done.
`lmon-timeout`		Specifies (in seconds) how often local monitoring of the DMF daemon is done if no response is received.
`retry-count`		Specifies the number of times the local monitoring script retries its probes of the DMF daemon. This values does not affect the `lmon-timeout` value.
